其实嘛…Jobli一直在吵的是他坚持一定要当
场试射之后才能效力射，问题是实际上是这
样吗？
这里我们在讨论的是反登陆条件下的阵地战
，所以请先不要乱入不相关的情况。什么打
新庄会偏到板桥去，拜托不要乱入。
那到底能不能？前面有人说了，二战时的日
军就做得到啊！靠着阵地把美军打得措手不
及。你说那是榴砲，迫砲不行？那我们来看
美军准则好吗？美军有说效力射之前一定要
试射吗？
没有。事实上，美军的准则很明确地把不试
射直接效力射当作一种奇袭手段，因为会让
对方来不及躲避。海陆的准则是这样写的（
陆军的也差不多，我就不重复了）：
“2-128. Firing corrections within the
transfer limits should be maintained
through registration, survey data, and
current MET message. When those data
are unavailable or inadequate, targets
should be attacked with observed fire,
since unobserved fires may be ineffective.
Surveillance should be obtained on all
missions to determine the results of the
FFE. If accurate, firing for effect without
adjustment is highly effective against
troops and mobile equipment because
damage is inflicted before the target can
take evasive action. All destruction
missions and missions fired at moving
targets must be observed, and FFE
should be adjusted on the target.”
简单地说，美国准则只有说实施效力射应有
前观观测确定落点和效果，并且供之后调整
，但并没有说必须要先试射，反而是说，如
果可以准确地直接进行效力射，对于敌部队
和机动装备的打击效果很高。
然后，准则也很明确的提到一些限制。弹药
消耗就不用说了，准则说供应量高时才能用
，但这对台湾不是问题，毕竟是在自己主场
。准则这样写：
“2-131. The amount of ammunition available
is an important consideration when attacking
targets. The controlled supply rate (CSR)
should not be exceeded except by the
authority of higher headquarters. When the
CSR is low, units should fire only those
missions that contribute the most to the
supported units' mission. When the CSR is
high, units may fire missions that include
targets that affect planning or future
operations and targets that require massing
fires without adjustment.”
然后，还有一些零星的限制和注意事项就
请自己Google，反正那些对于以阵地战进
行反登陆的一方而言不是太大的问题。
所以，不是我乱讲，是你们因为某些原因
根本不知道可以这样。
